PHP - 我需要通過url參數調用2個php函數 - 但是如何？

Question

我必須調用一箇舊的PHP函數與PC1加密，不幸的是我沒有說明或例子，只有PHP文件 - 並沒有PHP知道如何:(:(你可以幫助我如何調用加密和？解密通過URL參數的功能，我只需要顯示/打印的加密或解密的結果

這是舊找到代碼：

我試過了這樣的事情

public function index() 
    { 
     var $test; 
     $test = encrypt("Hallo","nhifgbcnlfglffmh"); 
     echo test; 
    } 

    $app = new PC1(); 
    $app->index(); 

但我得到解析錯誤：語法錯誤，意外的T_VAR在.... 我認爲return implode沒有返回一個字符串？

Answer 1

因爲它是所有的一類，你首先需要調用類

$app = new PC1(); 

Afther，你可以調用這個類裏面的函數：

$test = $app->encrypt("Hallo","nhifgbcnlfglffmh"); 

對於功能作爲工作網址參數你可以做到以下幾點： 網址：example.com?encrypt=Hallo

在它的鏈接檢查$_GET所以：

<?php 
$app = new PC1(); 
if(!empty($_GET['encrypt']) { 
    $encrypt = $_GET['encrypt']; 
    var_dump($app->encrypt($encrypt, "nhifgbcnlfglffmh")); 
} elseif (!empty($_GET['decrypt'])) { 
    $decrypt = $_GET['decrypt']; 
    var_dump($app->decrypt($decrypt, "nhifgbcnlfglffmh")); 
}
